Cool/Heat: Wrong fan, right fan

[53k]

When I bought my '64 R-1 Avanti a couple years ago the engine really howled at higher rpm (something like a 747 at full takeoff power). I saw that some PO had replaced the original fan with a seven-bladed one and the viscous clutch with one of the aftermarket ones being sold now. When I did my valve guide seal job recently I took the opportunity to replace the fan and clutch with an original. Last Saturday I made my first trip in it, about 120 miles on an Orphan Car tour. The car was much quieter, ran at the same temperature as before (180) even with the A/C running. Anybody want a seven bladed fan?

Your 7 bladed fan has a viscous clutch. Your other is a stock Stude {thermal fan clutch}. Much much better. jimmijim

That one looks like an AMC fan setup. All fans & clutches, including all 7 blades, are not created equal. I Installed a Corvette, 7 blade fan with thermal clutch on the GT, and was so impressed I later installed one on the 56J.
Of course, the 5 blade is working well for you, so if it ain't broke no need to fix it

Your Packard Water pump must have the same size centering "Hub" in the center as a Chevy. if you were able to bolt it on.
All Studebaker Engines have that larger, odd size centering hub, so the Thermal Clutch would have to be machined to fit.

Hi Rich,
No machining was required, other than a little grinding and pressing. For the 352, I ground the face of the water pump flange flat, then pressed the flange back toward the water pump to within about 1/16". At that point, the shaft protruded and served as the centering hub for the Hayden clutch.
For the 289, I ground the face of a spacer down even with the surface of a pulley, then drove a small socket into the center hole, which protruded enough to serve as a centering hub.
I realize the above explanations may sound confusing, but that's it in a nut shell. I always say, I can install air brakes on a bantee rooster if someone will hold it for me

I will have my son take pix tomorrow to post of the two fans on the cars.

Still learning how to post photos.

[JoeHall]

None of the photos came out very good, because my son's IPOD does not have a flash. Like l I said, still learning. http://i1259.photobucket.com/albums/...o/f9faccbc.jpg
